CHOICE Recommended Title, March 2019 This book brings together diverse new perspectives on current and emerging themes in space risk, covering both the threats to Earth-based activities arising from space events (natural and man-made), and those inherent in space activity itself. Drawing on the latest research, the opening chapters explore the dangers from asteroids and comets; the impact of space weather on critical technological infrastructure on the ground and in space; and the more uncertain threats posed by rare hazards further afield in the Milky Way. Contributors from a wide range of disciplines explore the nature of these risks and the appropriate engineering, financial, legal, and policy solutions to mitigate them. The coverage also includes an overview of the space insurance market; engineering and policy perspectives on space debris and the sustainability of the space environment. The discussion then examines the emerging threats from terrorist activity in space, a recognition that space is a domain of war, and the challenges to international cooperation in space governance from the nascent asteroid mining industry. Features: Discusses developments and risks relevant to the public and private sectors as access to the space environment expands Offers an interdisciplinary approach blending science, technology, and policy Presents a high-level international focus, with contributions from academics, policy makers, and commercial space consultants

"The book will offer the reader fresh perspectives on numerous aspects of space risk, covering both risks to Earth-based activities arising from space events (natural and manmade), and the risks inherent in space activity itself. Drawing on the expertise of contributors from a wide range of disciplines, the book will cover the nature of the physical risks, and appropriate engineering, financial, legal and policy solutions to mitigate them"--

This book shares a range of new and diverse insights on On-Orbit Servicing (OOS), and examines its implications especially from political, legal, economic, and security perspectives. OSS has been evolving rapidly and presents both challenges and opportunities, such as in-space repairs, refuelling, refurbishment of spacecraft and servicing satellites, which could play a critical role in extending satellite lifecycles, while also representing a valuable next step in debris mitigation. At the same time, many legal questions have arisen in connection with OOS: the need to prevent hostile actions under the pretext of OSS; the distinction between governmental and non-governmental OOS operators; the status of re-worked and recycled space objects; the issue of control in terms of operations performed in orbit, i.e., in the international sphere; the status of objects manufactured in orbit and applicable law, including liability and registration; and the impacts on insurance law and risk management. Finally, the book examines the implications of OOS for emerging space actors in the Global South, and recommends a paradigm shift to help developing countries fully recognise the necessity and urgency of being involved in discussions on OSS, as opposed to leaving it up to the developed space actors. This book will be of great interest to practitioners, academics, and students working in the space sector and related fields.

Space Commerce relates the story of private enterprise's unsteady rise to prominence as a major influence on world space policy and research. The first space race proved the technological and military prowess of the two superpowers; but since the 1970s that contest has been supplanted by a multinational struggle to command the commercial opportunities of space. The commercial space age was born in 1965 when Early Bird, the first commercial communications satellite, went into orbit. With characteristic ingenuity, American industrialists began to dream of garnering billions of dollars per year from space-based products and services. In the microgravity of space, they hoped, hitherto unavailable drugs could be produced that would revolutionize medicine; in the high vacuum of space, crystals of extreme purity could be grown in orbital laboratories, both for biological research and for application in the manufacture of advanced microcircuits. In this book John McLucas covers the broad sweep of space commerce, both the vision and the reality: the construction of communications satellites and their ground control stations; the sale and leasing of communications services; remote sensing and measurement of earth's processes; navigation by satellites, serving ships, airplanes, and automobiles; the design and deployment of space laboratories for scientific research and product development; and life science experiments to determine the effects of space habitation on humans. Drawing on his considerable expertise, McLucas brings a sober perspective to his assessment of the technological accomplishments as well as the challenges still faced by industry in space. He incorporates into his discussion an illuminating analysis of the economic and political impact of space commerce and its rapidly changing international character.

NASA's current missions to the International Space Station (ISS) and potential future exploration missions involving extended stays by astronauts on the lunar surface, as well as the possibility of near- Earth object (NEO) or Mars missions, present challenges in protecting astronauts from radiation risks. These risks arise from a number of sources, including solar particle events (SPEs), galactic cosmic rays (GCRs), secondary radiation from surface impacts, and even the nuclear isotope power sources transported with the astronauts. The serious early and late radiation health effects potentially posed by these exposures are equally varied, ranging from early signs of radiation sickness to cancer induction. Other possible effects include central nervous system damage, cataracts, cardiovascular damage, heritable effects, impaired wound healing, and infertility. Recent research, much of which has been sponsored by NASA, has focused on understanding and quantifying the radiation health risks posed by space radiation environments. Although many aspects of the space radiation environments are now relatively well characterized, important uncertainties still exist regarding biological effects and thus regarding the level and types of risks faced by astronauts. This report presents an evaluation of NASA's proposed space radiation cancer risk assessment model, which is described in the 2011 NASA report, Space Radiation Cancer Risk Projections and Uncertainties-2010. The evaluation in Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation considers the model components, input data (for the radiation types, estimated doses, and epidemiology), and the associated uncertainties. This report also identifies gaps in NASA's current research strategy for reducing the uncertainties in cancer induction risks.
